8.3 AT^SOPS Extended Operator Selection
AT^SOPS queries the present status of the MC55's network registration. Since basic operator selection services
are available with AT+COPS this command uses the methods of the Enhanced Operator Name String (EONS)
specification while handling operator name strings. Additional EONS related information is available with
AT^SIND.
AT^SOPS test command lists sets of five parameters, each representing an operator present in the network.
A set consists of
1. an integer indicating the availability of the operator,
2. specification of the source of the operator name <eonsOperator>,
3. operator name according to EONS Table,
4. Service Provider Name from the SIM Service Table and
5. numeric format representation of the operator.
Any of the parameters may be unavailable and will then be an empty field (,,).
The list of operators comes in the following order: Home network, networks referenced in SIM and other net-
works.
After the operator list the MC55 returns lists of supported <mode>s and <format>s. These lists are delimited
from the operator list by two commas.
If the test command is used while an ongoing GPRS transfer, traffic will be interrupted for up to one minute.
Command settings are effective over all serial interfaces of the MC55.
